Etymology: Gigantactis: Greek, 'gigas' or 'gigantos' = gigantic + Greek, 'aktis' = ray (referring to the unusually long first dorsal-fin spine that functions as a lure in this genus) (Ref. 86949).

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 5 - 6; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 5 - 6. Metamorphosed females distinguished by the following characteristics: length of illicium 340-447% SL; escal bulb with lightly pigmented truncated distal prolongation; 6-20 long distal filaments; escal papillae absent; proximal escal papillae absent; short dentary teeth (longest 1.3-3.4% SL, average 2.3% SL), arranged posteriorly in two longitudinal series; length of caudal fin rays less than 45% SL; weakly developed skin coverage of proximal part of caudal fin; caudal fin rays free nearly to base (Ref. 86949).
Appear to be active predators which feed on midwater fishes, including Cyclothone acclinidens, Triphoturus mexicanus and Bathylagus stilbius; cephalopods like Vampyroteuthis; and various invertebrates like amphipods, natant decapod crustaceans and coelenterates (Ref. 4525). Maximum length for female from Ref. 41361.
